A ground fault circuit interrupter is a type of circuit breaker installed directly on an electrical outlet. It automatically shuts off power to the receptacle if there is an electrical fault. GFCI outlets provide enhanced safety and peace of mind by helping reduce the risk of shock and electrocution. Use the following guide to learn more about these devices and why you should have an electrician upgrade the existing units throughout your home.

How Do GFCI Outlets Work?

A traditional outlet has two, three-pronged plug-ins; a GFCI receptacle has this same layout in addition to a “test” and “reset” button. Under normal conditions, electricity flows uniformly throughout your home's wiring. However, a ground fault can occur when there's a break in the grounding path due to worn insulation, conductive dusts, water, and other issues. When this happens, electricity surges through the wires and follows the easiest path to the ground, which could end up being through the person trying to plug in a device. 

A GFCI outlet has a sensor that tracks the voltage streaming through the wiring. If it detects any variation from the normal current, the ground fault circuit interrupter engages an internal switch, which disconnects the electricity flowing to the receptacle. The testing and reset buttons allow you to check that the outlet is working and reset it after the internal switch shuts off down the unit's power.

What Are Some Main Reasons to Upgrade Old Outlets?

GFCI outlets make homes safer since older units do not have the same built-in safety mechanisms. They help prevent shocks and electrical fires, and the National Electrical Code mandates that they be installed in certain parts of a building. When an electrician upgrades the receptacles in your house, it reduces the risk of electrical injuries, burns, and fires while also bringing the dwelling up to code.

What Rooms Benefit From Them?

The NEC requires GFCIs in any location that is vulnerable to moisture. This includes kitchens, bathrooms, laundry rooms, basements, crawl spaces, and garages. Outdoor outlets must also be GFCIs. An electrician can install these quickly and easily with no disruption to your household and daily activities.
